Implemented an algorithm for solving a system of linear equations in MPI. Equations of the form Ax = b . I can not find a large matrix, preferably square with the vector of the right side. Ie, for example:

 2 4 5 6 5 3 4 1 5 и вектор 2 1 9 8 3 3 8 3 2 5

I found this resource: https://www.cise.ufl.edu/research/sparse/matrices/ , but I don’t understand how you can reformat it in the format I need, those I’ve come across will be very grateful for the dataset or interpretation how to reformat.
